Creating Code-Behind file - aspx.cs

Question

I am using VS2010 and I created a ASP.net empty web application, but I cannot for the life of me get it to generate an index.aspx.cs file. I double click any control in the view and I just get nothing. What could I possibly be missing? I used to be able to just double click on a control and it would automatically generate the .cs if it didn't exist.

Answer 1

When you add a new item to the project and pick "web form" as type, you should have both index.aspx and the code behind file. Double-clicking controls does not generate the code behind file, it only adds event handlers to it. Take a look at this walkthrough.

Answer 2

In your project file (csproj), make sure that you have the DependentUpon tag which indicates that the aspx.cs file depends on the aspx file. Here is an example:

<Compile Include="dir\myFile.aspx.cs">
      <DependentUpon>myFile.aspx</DependentUpon>
      <SubType>ASPXCodeBehind</SubType>
</Compile>

This worked for me.
